Managed to undo two pinion gear nuts today! Feel like I deserve a medal!

Armed with a 2 meter exhaust pipe section, wedged under a full water tank base, applied heat the sods came loose after much swearing.

But seriously, who puts these on? Or do they work themselves tighter with rotation and crud ingress?
Any way to prevent this lunacy?

They are supposed to be 150ft/lb. But I've had one so tight that 8ft of scaffold pipe and me on the end wouldn't move it.
I used a 4" angle grinder and a worn disc to cut a corner off the nut.

Mine came off really easy, but then again I paid someone else to do it

Most healthy people can apply 150ft/b with a 250mm breaker bar. There's something sinister in that BMC steel. The souls of a thousand minis rusting, the pudding stirrir time forgot. Or the dreaded rattle gun, wielded by mowog the gorilla!

We should all be so lucky as to have felt the sting of a seized pinion nut, makes you remember there are greater forces at work.

Today I am a different man, after conquering my own sword in the stone.

Thanks for the imagery. Next time I am having an offer with my mini I will blame it on mowog the gorilla.

But seriously what is worse having it to tight or finding it loose wondering why it didnt fall off.

They're put on at 150ft/lbs. Then sitting there for 40 years makes them 'bind' a little. The issue isn't getting a long enough lever arm, the issue is finding something to hold the box!

I bolt a 3M length of 150mm wide conveyor side channel onto mine, it ain't going anywhere...
I used to stick it under the back of my boat trailer and wind the front jockey wheel down, that worked fine. Until TK bought the boat and towed it to Brissy.

I use a special tree with a fork in the trunk just above the ground. The gearbox sits nice and snug in the fork while you heave on the breaker bar

I know someone who drilled 4 holes in his workbench and bolts the gearbox to it. Works for him...

I used to use any/all the unwilling helpers around the house, wife, kids etc, to stand on the box which was on the floor. Used to work OK most of the time. Used my elderly dad one day and catapulted him off the box and down he went onto the floor. Thought I had done some serious injury to him as I had engine and gearbox bits scattered everywhere. Amazingly, he missed all that and was unhurt.

After that, I made a steel frame that the box slides into. Works an absolute treat and no more accusations of wife, child or elder abuse!

Or 10 tonnes of water tank. Common problem with some creative solutions. Future shed will include some m12 bolts cemented into the ground so I can bolt a frame over the box.

That sounds like a great idea .
